the combination with a transmission gear case having a. dovetail slideportion thereon, a motor mounting having a complementary dovetailportion thereon adapted to coact with the dovetail ortion on the casing,said dovetail portions ing so directed that the mounting will onlybecapable of sliding in the direction of the longitudinal axis of themotor, and means for locking the mounting -in position to form the solesupport.

In ay device of the class described including a base frame, atransmission gear system housin having perpendicular walls mounted onsai frame, a motor, meansfor securing said motor on one of theperpendicular Walls of said housing, said motor being axially movable 0nsaid wall and solely supported thereby.

In testimony whereof, I have signed my name to this specification.
